IMPROVEMENT IN HORSE-RAKES,

iiilgt Stlgjthtle tristan tu in tlgest Estan; @that tnt making nati ai the samt.

TtQlALL WHOM IT MAY CONCERN: Be it known that I,.C1 IAaLEs Srsnnsrr, of the county of Cook, and in the State of Illinois, have invented it 4new and useful Improvement in Horse Hay-Rakes 'and do hereby deelarefthatl the following is au exact, full, and clear description of the same, reference being had to the accompanying drawings, making part 'of this specification..

My invention relates to the class of revolving rak'es, and is animprovement upouthat patented November .25, 1862, to A. H. Chaplin, and numbered 36,992, and in which was employed, forlthe purpose of catching and- Vsustaining the rake after a revolution had been completed, and to prevent a secondrcvolution before any hay had been gathered, a piece ofmetal, bent intosuch qnndrangular form that eneoithelonger sides inclined tvards the other, the end of the metal being free, so that this inclined side, when pressed b'ya tooth of the revolving rake, wasfored o utot' ijs ,normal position until the tooth had pa sse d,whenthe rlsilienee'of lthe spring caused.4 ttc resume its place, and so form a lock or catch to prevent the teeth from turning b ack again.

There are serious objections to this device,' and which my invention is designed eifectually to remedy, the yobjections being that the action of these met-al springs upon the same wooden Vteeth at'each revolutionof the :rake is such as to rapidly vscrape and cut themaway at their points of contact, and so destroy them, and the spring so formed being an irregular open hoop, having its edges i'acing towards the hay which is collected upon 4the teeth, clogs` the action of the rake bycatching the hay and gathering it around itself. Y i Also, the'action of the teeth upon'the peculiar spring of Chaplin (which performs the double dutyof ftpring and loch) tends, after much use, to change its form,so as to -lessen the `inclination of the inclined or cam side, and so to gradually destroy its cilieien'cy.

The wear which takes place on those teeth which come in contact with the edges of this spring, besides ultimately cntting or ehaiing away thel teethf-"as above stated, and rendering them useless-or requiring to be replaced, also makes them irregular on theirfsurface, and full of nicks and cuts, and causes them to retain the fhay, &c., improperly at times, when they should freely discharge it. l By my i'mprovement,`I-alsoiavoid any scraping or abrasion of metal aganst'the wooden teeth, and present a dat, solid face against the accumulating hay, instead of twothin metailicieglges, with a space between them, and one of these vibrating at every revolution of the teeth. j

' In the drawing is represented a horse-rake, of ordinary const-rnctinin the mainand also containing my improvements. Y

A A A" designate the teeth ipon the usual revolving shaft; B 13, the handles, with the usualV dropbar, C, attached. D D-are wooden blocks, broader at their base thanat -their tops, one side of cach blgck, namely, that against which one of thorevolving teeth must bear,'ha ving an inclination upwards towards its opposite sidc, the width of this block or wedge-piece being, however,.less at its base than the space betweenl the teeth. Each of these blocks is rigidly-secured ina. vertical position to the forward' end ofajlat spring, E, which, towards its rear end, is bolted or otherwise firmly fastened to the handles B B, respectively; The inclined -face of the bloch, which during eac'h revolution abrades or chafes against the toot-h, is of wood only, so that no metalis in position to wear the teeth away, the spring .being so applied'and located as to accomplish all the object attained by Chaplins or any other form of spring, but being entiifely out of the Way of possible'contact with the teeth. l

The operation is as follows:

rl'he horse, being attached to the rake in the usual way, and the machine p ut in motion, as the rake com- -mences to revolve, the narrow ends of the blocks D D permit the rake to pass over them, the blocks severally entering between two adjacent teeth, and that tooth whichiis in immediate proximity to the inclined side of the block'bears against' it with a pressure constantly increasingas the revolution ofthe rake continues, and thus presses outward from the handle B, and from its own normal position the spring E, until the tooth has passed beyond the base or broad part of kthe block, when the force of the spring causes it suddenly to y back to its place, 'thus`bringing tle base of '111e` bloek beh-ind the tooth, and securing the rake rmly inritspositon. I do not claim 'anything contained in the patent of Chaplin, above mentioned; but I clim the springs E E, applied as shownfincombination wh solid wooden blocks D D, havingeach a rigid inclined face, the whole eonstructed and arranged to operate as and for the purpose setlforth.'
